Radio Devices - EMS FIRECELL Programming Manual

3.3 Radio Devices

The Radio devices have LED indicators and log on buttons which perform certain functions. This
section explains their functionality.
Log On Button
The Log On button is used for adding devices to the system. The required procedure for
achieving this is detailed within the 'Quick Step by Step To System Programming Guide' section of
this manual. The action of pressing the log on button for 2 seconds will revert the device to its
commissioning frequency channels to allow addition to the system, and also illuminate the log on
LED.
NOTE: Care should be taken not to press this button when the unit is already added to
the system and operating on its allocated frequencies as this frequency information will
be lost and default to the devices commissioning channels.
Log On LED
The LED is allocated next to the Log On button on the detector and sounder. This will illuminate
when the log on button has been pressed for two seconds. On a call point the Alarm LED on the
front of the device is utilised as indication that the Log On button has been pressed for 2 seconds.
Alarm LED
The Alarm LED will switch on in the event of an alarm condition detected by the device. The
device controls this indication for the first 10 seconds of the alarm condition. After the initial 10
seconds the LED indication is completely controlled by the connected Fire Alarm Control panel and
will therefore turn on and off as instructed to do so by the programming in the panel.
Audio Detect Enable Switch
An audio detect switch is located on the sounder base. This feature can be enabled for each of
the sounder output stages 1 or 2 using the corresponding number on the 2 way switch. When
enabled the unit carries out tests when operated, by checking the actual sound output. If no
sound is detected within 10 seconds of the sounder base being switched on a fault will be
indicated at the control panel. This feature should be disabled for a beacon only unit (Switch 1
and 2 off).
Output LED
An Input/output device has a red LED associated with each relay output. If the LED enable
button is pressed and the output is activated the LED will illuminate. The LED's will be
illuminated for 10 minutes and then automatically time out.
Input Fault
An Input/output device has a yellow fault LED associated with each input. If the LED enable
button is pressed and the input is in a fault condition the LED will be illuminated. The LED's will
be illuminated for 10 minutes and then automatically time out.
Input Switch Closed
An Input/Output device has a red switch closed LED associated with each input. If the LED
enable button is pressed and the input is closed the LED will be illuminated. The LED's will be
illuminated for 10 minutes and then automatically time out.
